摘要：

A regioselective transition metal mediated domino reaction of carbon nucleophiles with oxalic acid-bis(imidoyl)chlorides is reported. This reaction provides a convenient access to E-configured 5-ylidenepyrrol-2(5H)-ones. Without the presence of cobalt(II) or nickel(II) salts, open-chained products were obtained. The regioselective cyclization is controlled by the coordination of the nitrogen atoms of the 1,4-diazadiene system to the transition metal.
